The shell script that is /sbin/mount.tmpfs shows up very unfavourably in bootchart: http://www.harald-hoyer.de/personal/blog/2011-02-03-fedora-rawhide-bootcharts It would be fantastic if we could get rid of that script (and especially the grep in it), and the selinux label magic could be done in mount instead, in simple and fast C code.
Note that the mount.tmpfs script is originally developed for bug #476964.
Fixed by upstream commit 086f6471089b3487f46309b401867b3dae7d1551. The fedora version will be updated after upgrade to the final v2.19 (next week).
Awesome, thank you. You rock! /me strikes one more item of his list.
