%general-entities; ]> Util-linux The FHS recommends using the /var/lib/hwclock directory instead of the usual /etc directory as the location for the adjtime file. To make the hwclock program FHS-compliant, run the following: mkdir -pv /var/lib/hwclock Prepare Util-linux for compilation: ./configure \ ADJTIME_PATH=/var/lib/hwclock/adjtime \ --enable-write \ --disable-chfn-chsh \ --disable-login \ --disable-nologin \ --disable-su \ --disable-setpriv \ --disable-runuser \ --docdir=/usr/share/doc/util-linux-&util-linux-version; --enable-write This option allows the write program to be installed. --disable-* This option disables various programs Compile the package: make To test the results, issue: chown -Rv nobody . && su nobody -s /bin/bash -c "PATH=$PATH make -k check" Install the package: make install Move the logger binary to /bin as it is needed by the CLFS Bootscripts package: mv -v /usr/bin/logger /bin Installed programs Installed libraries Installed directories addpart, agetty, blkdiscard, blkid, blockdev, cal, cfdisk, chcpu, chrt, col, colcrt, colrm, column, ctrlaltdel, delpart, dmesg, eject, fallocate, fdformat, fdisk, findfs, findmnt, flock, fsck, fsck.cramfs, fsck.minix, fsfreeze, fstrim, getopt, hexdump, hwclock, ionice, ipcmk, ipcrm, ipcs, isosize, kill, last, lastb (link to last), ldattach, logger, look, losetup, lsblk, lscpu, lslocks, mcookie, mesg, mkfs, mkfs.bfs, mkfs.cramfs, mkfs.minix, mkswap, more, mount, mountpoint, namei, nsenter, partx, pg, pivot_root, prlimit, raw, readprofile, rename, renice, resizepart, rev, rtcwake, script, scriptreplay, setarch, setsid, setterm, sfdisk, sulogin, swaplabel, swapoff, swapon, switch_root, tailf, taskset, ul, umount, unshare, utmpdump, uuidd, uuidgen, wall, wdctl, whereis, wipefs, write libblkid.[a,so], libmount.[a,so], libuuid.[a,so] /usr/include/blkid, /usr/include/libmount, /usr/include/uuid, /usr/share/bash-completion, /usr/share/doc/util-linux-&util-linux-version;/getopt, and /var/lib/hwclock Short Descriptions addpart Informs the kernel of a new partition addpart agetty Opens a tty port, prompts for a login name, and then invokes the login program agetty blkdiscard Discards sectors on a device blkdiscard blkid A command line utility to locate and print block device attributes blkid blockdev Allows users to call block device ioctls from the command line blockdev cal Displays a simple calendar cal cfdisk Manipulates the partition table of the given device cfdisk chcpu Utility to configure CPUs chcpu chrt Manipulates real-time attributes of a process chrt col Filters out reverse line feeds col colcrt Filters nroff output for terminals that lack some capabilities, such as overstriking and half-lines colcrt colrm Filters out the given columns colrm column Formats a given file into multiple columns column ctrlaltdel Sets the function of the Ctrl+Alt+Del key combination to a hard or a soft reset ctrlaltdel delpart Asks the kernel to remove a partition delpart dmesg Dumps the kernel boot messages dmesg eject Eject removable media eject fallocate Preallocates space to a file fallocate fdformat Low-level formats a floppy disk fdformat fdisk Manipulates the partition table of the given device fdisk findfs Finds a file system by label or Universally Unique Identifier (UUID) findfs findmnt Lists mounted filesystems or searches for a filesystem findmnt flock Acquires a file lock and then executes a command with the lock held flock fsck Is used to check, and optionally repair, file systems fsck fsck.cramfs Performs a consistency check on the Cramfs file system on the given device fsck.cramfs fsck.minix Performs a consistency check on the Minix file system on the given device fsck.minix fsfreeze Suspends and resumes access to a filesystem fsfreeze fstrim Discards unused blocks on a mounted filesystem fstrim getopt Parses options in the given command line getopt hexdump Dumps the given file in hexadecimal or in another given format hexdump hwclock Reads or sets the system's hardware clock, also called the Real-Time Clock (RTC) or Basic Input-Output System (BIOS) clock hwclock ionice Gives and sets program I/O scheduling class and priority ionice ipcmk Creates various IPC resources ipcmk ipcrm Removes the given Inter-Process Communication (IPC) resource ipcrm ipcs Provides IPC status information ipcs isosize Reports the size of an iso9660 file system isosize kill Send a signal to a process kill last Shows which users last logged in (and out), searching back through the /var/log/wtmp file;
