Fix example statement (deny _writing_, not reading); also fix name of "syscall_limiter" project.

comment How to prevent a process from writing files
Note that secure approach is to whitelist syscalls, not to blacklist them. If too much is denied, external unsanboxed helpers can be used to assist the program. With LD_PRELOAD such helpers can be made transparent to the program we running.

comment How Debian package should create user accounts?
The link is too general. I already tried to quick-search like "Debian policy useradd" or "Debian policy create new user" but have not found anything useful. Please include the link to section that describes using "adduser" (or useradd?) to postinst (or preinst?), how the user should be named, what other things I need to think about...

comment Are there alternatives for `dd`?
ddrescue - - -> Infile and outfile are the same., ddrescue /dev/stdin /dev/stdout -> Infile and outfile are the same.. Bad beginning of the story...

comment Are there alternatives for `dd`?
1. bs=1 => the whole pipeline is slow. For example I may want to dump video file starting from some exact frame. 2. "It takes some arithmetic" => not very suitable for oneliners and routine shell commands.

comment Are there alternatives for `dd`?
The main wrong thing is inability to seek to or skip fractional blocks. Second wrong thing that status=noxfer is not default and is broken and that I need iflag=fullblock (omit in some script => broken data).
