Use "GROUP:=" instead of "GROUP=" and see if that fixes your custom rule. oops, need to assign this to me... ok, now can mark "test-request"... ugh... am not having fun with bugzilla today... greg, it works perfectly.... beautiful. the udev man pages mention using that := syntax to "disallow later changes", but in practice i've never used it. looks good here now. many thanks. phil great, I'll mark this as closed then. |
Certain devices, e.g. sr[0-9]*, cannot be created outside of group disk. Using a local rule with an alternate GROUP specifier, e.g. GROUP="cdrw", udev does not honor the GROUP specifier. I am specifically interested in replacing this stock rule on 50-udev.rules: BUS=="scsi", KERNEL="sr[0-9]*", PROGRAM="/etc/udev/scripts/cdsymlinks.sh %k", SYMLINK+="%c{1} %c{2} %c{3} %c{4} %c{5} %c{6}" with this rule in 10-local-udev.rules: BUS=="scsi", KERNEL="sr[0-9]*", PROGRAM="/etc/udev/scripts/cdsymlinks.sh %k", SYMLINK+="%c{1} %c{2} %c{3} %c{4} %c{5} %c{6}", NAME="%k", GROUP="cdrw" in order to create /dev/sr0 as root/cdrw (uid/gid)and not root/disk, while also creating the convenient symlinks output by cdsymlinks.sh. My 'cdsymlinks.sh sr0' output is "cdrom1 cdrw dvd dvdrw" and those symlinks are created and pointing correctly to /dev/sr0. The larger goal is to eliminate non-privileged users access to group disk by placing devices like burners into an alternate group such as cdrw. Reproducible: Always Steps to Reproduce: 1. 2. 3.
