distrib/miniroot: install.sub
Log message:
Prefetched sets are stored by root, but are read by an unprivileged
user during the actual install phase. Add a check to the selection
of the prefetch area to ensure the unprivleged user can read files
from there.
Move the selection logic to its own function prefetcharea_fs_list()
which returns a unique list of candidate filesystems, or with rc=1.
While at it, remove /var/tmp from the potential list of candidates
because it's a symbolic link to /tmp since 2014.
Change install_files() to loop over the candidates and check if it
can read a test file, otherwise clean up and skip this filesystem.
Problem found by benno@ whose upgrade failed due to /usr/obj being
owned by build:wobj and permissions that prevented the unprivileged
user to read the prefetched set files from there.
discussed with and OK benno@ halex@ tb@
