Hi, I've been optimizing a system for flash, and wanted to have /var/run be a tmpfs mount, so that these writes to not wear down the flash/ssd. I noticed only a few initscripts create their own directory in /var/run/ if they need it. I've read http://fedoraproject.org/wiki/FCNewInit and http://fedoraproject.org/wiki/FCNewInit/Initscripts but neither one mentions anything about /var/run being tmpfs. Browsing the FSB does not yield anything either. Should I consider it a bug if an initscript is using a subdirectory in /var/run/ but does not check/create it on being called with start? And is there a convention for when to use files directly in /var/run/ and when to create a subdirectory? Paul
You could use the readonlyroot feature and customize /etc/rwtab, /etc/sysconfig/readonly-root
