Re: [PATCH] devfsd, compiling on glibc22x
While on the subject of devfs:
- it doesn't seem to have any entries for raw devices:
/dev/rawctl, /dev/raw/raw1, etc
- when I upgraded to glibc 2.2 (via a rpm) in RH 7.0
this line in /etc/devfsd.conf caused devfsd to
seg fault:
"LOOKUP ^cdrom$ CFUNCTION GLOBAL
symlink ${mntpnt}/cdroms/cdrom0 $devpath"
Rebuilding devfsd didn't help.
