comment How can I create an encrypted, file-system–agnostic, mountable volume?
@Sparhawk I am not sure whether I understand the question correctly as I have already given such a command (the "normal" one without any fancy stuff) in my answer.

@Sparhawk Your don't lose information when backing up ext4 to ext3; most ext4 advantages are not visible to the VFS. But ext3 is slower. Problems arise in extreme situations only: If you have files or directories which exceed the ext3 limits (file size / number of subdirectories).

comment How can I create an encrypted, file-system–agnostic, mountable volume?
@Sparhawk That's a completely different question and most probably answered here elsewhere in detail. Short version: You don't get (all) the ext4 advantages when remounting ext3 as ext4. If you turn on the ext4 features then the volume cannot be mounted as ext3 any more. Some features affect newly created files only. Thus if you create a file system anyway and there are no good reasons to stay with ext3 then create it as ext4.

@Sparhawk If the suggestion works for you now then you may (upvote and) accept it to "close" this question...

@Sparhawk That is very strange if the luksFormat command before did not return an error. You can also try isLuks and luksDump on the device.

comment TAB autocomplete on sudo sh
What does "stops working" mean exactly? sudo sh / + TAB does not result in path autocomplete? What is the output of complete -p sudo?

comment Redhat find process memory usage
If I search for "memory usage" on this site I get 224 results. Don't you think you should have searched for the answer before you ask that question one more time?

comment What is a process GID and what purpose does it serve?
@ntrrgc See ps -e -o pid,group,supgrp,args and man sudo (search for "groups"). In order to start a process with groups you don't belong to you must be the superuser (at least indirectly via sudo or similar).

comment What is a process GID and what purpose does it serve?
@ntrrgc If www is made the primary group of a process then all files, directories (and so on) which the process creates have www as their group (unless this is overwritten by the SGID bit of the parent directory). If www is the only group this process belongs to then it probably has access to fewer objects.

comment unexpected bash behaviour after console login (openSUSE)
bash as a shell runs under a terminal... When installing openSUSE you can configure whether automatic login shall happen. I know that from X only not for the console. Do I understand you correctly: You start the PC and get to a shell prompt without enterting user name and password?

comment tproxy per user
Is your "box" a router or the system you are working on? You don't make that clear and the point is: --uid-owner makes sense on a user system only, PREROUTING on a router only. The page you refer to is about router configuration.

comment tproxy per user
@cadrian I don't understand the problem. I don't know tproxy but it probably is a proxy server listening in the localhost interface. Thus your rule should work. I assume it doesn't; otherwise you wouldn't have asked... Please provide the output of tcpdump -i lo -n. Are there INPUT rules blocking traffic to lo?

comment Option “user” work for mount, not for umount
/proc/self is just a symlink to /proc/$PID of the calling process. About the man page problem: Feel free to improve the text. I am sure the maintainers will be happy.

comment What is the best practice for adding disks in LVM
@frostschutz Well attentive but playing smart-ass: The space "available for wasting" is not "dev size modulo PE size" but "(dev size minus metadata space (384K)) modulo PE size". Whether that results in more or less depends, of course.
