Normally using loop-aes along with other modules shouldn´t be a problem. Modules are not a part of the kernel image and thus can be patched/compiled/loaded separately as needed. > Are there any deeper conflicts between mainline loop and loopAES , so > it's not possible to use them both at the same time? The point with kernel 2.6.28-11-generic as compiled by ubuntu 9.04 is the integration of the loop module into the standard kernel image. Compiling the latest loop-aes sources works quite fine and results in a loop.ko module. When trying to load this module an error occurs and dmesg says: loop: exports duplicate symbol loop_unregister_transfer (owned by kernel) Since this type of error isn´t new, got it on SuSE plenty of times, I remember there is some condition for use of loop-aes unsatisfied. Current standard kernel is configured with CONFIG_BLK_DEV_LOOP=y whereas loop-aes needs it to be a module or left out (m/n). > Installing an additional module is easy ( especially, if dkms is part > of the distribution); compiling an own kernel is time consuming and too > difficult for many users. In case you made loop-aes work on ubuntu 9.04 I´d like to see your changes. So far I got the kernel sources, reconfigured the loop to be off the kernel and up to now the compile process runs for 90 minutes. > Perhaps, the current procedure of installation discourages many from > using loopAES ... The current development of ubuntu discourages me from going on using it. Kind regards, Peter -- Psssst! Schon vom neuen GMX MultiMessenger gehört?
