[Pkg-sysvinit-devel] Bug#272066: Not delete symlinks to directories in /var/run/ ?

[Thomas Hood]

[Please forgive the duplicate, but I first sent this with a useless
Subject line.]

debian-devel readers: There is a proposal (#272066) that bootclean.sh's
cleanrun function not delete symlinks under /var/run/ whose targets are
directories.  The function already refrains from deleting directories.
Any objections?  Please reply to 272066 at bugs.debian.org, not to the list.

"! -type d" matches everything (including symbolic links) except directories.
"! -xtype d" in the absence of "-L" matches everything except directories
and symbolic links to directories.  Thus IIUC the latter eliminates the need
for the former.

I am cc:ing this to debian-devel in order to solicit opinions.
