udev.permissions and cdrecord

a part of my udev.permissions:

# optical devices
sr*:root:optical:660
scd*:root:optical:660
pcd*:root:optical:0660
cdrom*:root:optical:0660
dvd:root:optical:0660
rdvd:root:optical:0660
cdroms/*:root:optical:0660

# disk devices
hd*:root:disk:660
sd*:root:disk:660
dasd*:root:disk:660
ataraid*:root:disk:660
loop*:root:disk:660
md*:root:disk:660
ide/*/*/*/*/*:root:disk:660
discs/*/*:root:disk:660
loop/*:root:disk:660
md/*:root:disk:660

I have

disk::6:root,alex
optical::93:alex,hal

in /etc/group.

yet everytime the user alex tries to cdrecord, he gets:

$ cdrecord dev=/dev/hdc blank=fast

cdrecord: Cannot allocate memory. Cannot get SCSI I/O buffer.

however the above command works for root.

Re: udev.permissions and cdrecord

udev.permissions is history, do your changes to udev.rules or just add yourself to optical group.

Re: udev.permissions and cdrecord

I deleted udev.permissions.
In udev.rules I have now:

# permissions for IDE CD devices
BUS=="ide", KERNEL=="hd[a-z]", SYSFS{removable}=="1", PROGRAM="/bin/cat /proc/ide/%k/media", RESULT=="cdrom*", NAME="%k", GROUP="optical"

and then

$ gpasswd -a alex optical

but I get the same error in cdrecord.

Re: udev.permissions and cdrecord

have you run pacman -Syu after install, if not please do this.

Re: udev.permissions and cdrecord

tpowa, is the objective to upgrade udev?
because if it is, I got this after pacman -Syu:

:: udev: local (071-4) appears to be newer than repo (current/068-4)

do you think it's worth to upgrade the other packages anyway?
