Debian bullseye: changes in util-linux #newinbullseye
Continuing with #newinbullseye. One package that isn’t new but its tools are used by many of us is util-linux, providing many essential system utilities. There is util-linux v2.33.1 in Debian/buster and util-linux v2.36.1 in Debian/bullseye, and as usual there are many new features and options available.
I don’t want to replicate the release notes provided by upstream, instead make sure to check out the Release highlights sections in the following release notes:
Tools that have been taken over from / moved to other packages
Debian’s util-linux source package provides new binary packages: eject (and eject-udeb) and bsdextrautils. The util-linux implementation of /usr/bin/eject is used now, replacing the one previously provided by the eject source package.
Overall, from a util-linux perspective the following shifts took place:
col, colcrt, colrm, column: moved from binary package bsdmainutils to bsdextrautilseject: moved to binary package ejecthd: moved from binary package bsdmainutils to bsdextrautilshexdump: moved from binary package bsdmainutils to bsdextrautilslook: moved from binary package bsdmainutils to bsdextrautilsul: moved from binary package bsdmainutils to bsdextrautilswrite(.ul): moved from binary package bsdmainutils (named bsd-write) to bsdextrautils
Deprecated / removed tools
Tools that are no longer shipped as of Debian/bullseye:
/usr/bin/rename.ul(rename files): use e.g. rename package instead, see #926637 for details regarding the removal/usr/bin/volname(return volume name for a device formatted with an ISO-9660 file system): useblkid -s LABEL -o value $filenameinstead/usr/lib/eject/dmcrypt-get-device: no replacement available
New tools
Debian’s bsdutils package (which is provided by the util-linux source package) provides a new tool from util-linux:
scriptlive: re-execute stdin log by a shell in PTY session
The new tools lsirq + irqtop (to monitor kernel interrupts) sadly didn’t make it into util-linux’s packaging of Debian/bullseye (as without per-CPU data they do not seem mature at this time). The new hardlink tool (to consolidate duplicate files via hardlinks) won’t be shipped, as there’s an existing hardlink package already.
