It's a pity that there is no kernel support for synching one filesystem (or maybe a few filesystems). I recently had a situation where I was doing a backup to a USB flash device and I decided to install some Debian packages. The sync() didn't complete until the backup completed because the write-back buffers were never empty! If dpkg had only sync'd the filesystems used for Debian files (IE ones on the hard drive) then the package install would have taken a fraction of the time and I could have used the programs in question while the backup was running. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/ -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe".
