One day I was unable to install updates because all the free space disappeared from my rootfs. AFAIK I shouldn’t have too many large stuff stored on this file system so I decided to figure out what is going on.
This should be an easy task but it took a while for me to figure out how to actually do it:
xbps-query --regex -p installed_size -s '.*' | sort -k2 -h
With this I found arm cross gcc toolchain was installed but as long as I use docker for devenv isolation I don’t actually need this any more.
As ncdu pointed out I have several versions of the linux kernel installed
(headers and modules). voidlinux keeps those to be safe. There is no
automated way that xbps uses to take care of these but there is a tool
named vkpurge:
sudo vkpurge rm all
(This won’t delete the current version.)
I used this tool but it left out most of the files from the 4.19.x linux
kernel series. Using xlocate I confirmed those were orphaned, so I
removed them by using direct commands.
With all these I managed to free up 11GB disk space! A lot of unneeded
stuff was hanging around under /usr/lib/modules and /usr/src.
