I quickly looked at Alon Bar-Lev's page at http://wiki.tuxonice.net/EncryptedSwapAndRoot and it appears to do the right thing. My earlier comments about problems arising out of mounting a "permanent-storage-device" prior to to resume, seem to be completely avoided by Alon Bar-Lev's script. That is because it appears to mount RAM disk only, and any "changes" to such RAM based device vanish on resume. So no inconsistency between RAM-after-resume and "permanent-storage-device" can occour. The initrd created by loop-AES' build-initrd.sh script needs to mount a "permanent-storage-device" to load programs that were intentionally omitted from initrd. The reason why it was done like that was to make the initrd as small as possible and also make it kernel version independent. At least on some setups the RAM occupied by initrd can't be freed, so making initrd small was really RAM saving feature. Does anyone have any idea how big that initramfs is that contains by Alon Bar-Lev's script and other needed programs+bits. And also, is that RAM free-able? -- Jari Ruusu 1024R/3A220F51 5B 4B F9 BB D3 3F 52 E9 DB 1D EB E3 24 0E A9 DD - Linux-crypto: cryptography in and on the Linux system Archive: http://mail.nl.linux.org/linux-crypto/
