Hi all, I'm the maintainer for the Arduino IDE in AUR, which manages the Arduino board (see arduino.cc). It needs rxtx to write to it, and uses lock files. Now, lock files can be created only by root, because /var/lock is root.root/755, so arduino can be run only by root, and it is not good.
I looked around in rxtx documentation, and saw that it expects /var/lock to be root.uucp/775, so I checked for uucp group, which doesn't exist by default. I found on the Arch wiki (http://wiki.archlinux.org/index.php/UID_and_GID_List) that uucp has a reserved user/group, so I grepped through /var/abs to find out who creates the group, and it is hylafax, which has definitely nothing to do with arduino and such. Also, in post_remove() the user and group are deleted, which would make it a dependency for arduino. Looking through the FHS I found this page: http://www.pathname.com/fhs/pub/fhs-2.3.html#VARLOCKLOCKFILES It references uucp, even though it doesn't say it should be the default GID, but to make it usable for apps like rxtx I think yes. What I propose is: - adding the uucp UID/GID by default in passwd/group - removing the relative sections from hylafax (in both PKGBUILD and hylafax.install - changing the GID for /var/lock to uucp RFC... bardo _______________________________________________ arch mailing list arch@archlinux.org http://archlinux.org/mailman/listinfo/arch
