Start working on virtual consoles/TTYs.
...
This is a mess right now, but I'd rather commit as I go.

Add a VFS::absolutePath(InodeIdentifier).
...
This is pretty inefficient for ext2fs. We walk the entire block group
containing the inode, searching through every directory for an entry
referencing this inode.
It might be a good idea to cache this information somehow. I'm not sure
how often we'll be searching for it.
Obviously there are multiple caching layers missing in the file system.

Canonicalize the path used by sh.
...
With a bunch of LibC work to support the feature. LibC now initializes
AK::StringImpl by default. It's now fine to use AK in LibC/Userland! :^)

Implement loading of linked ELF executables.
...
This took me a couple hours. :^)
The ELF loading code now allocates a single region for the entire
file and creates virtual memory mappings for the sections as needed.
Very nice!

Add a very hackish /proc/PID/stack.
...
It walks the stack and identifies anything that looks like a kernel symbol.
This could be a lot more sophisticated.

Add gettimeofday() syscall and LibC wrappers gettimeofday() and time().
...
This only has second accuracy right now, I'll work out subseconds later.

Remove old DatBuffer class.
...
(also increase the number of sectors loaded by the bootloader in the
since I just noticed we were at the limit. This is not the ideal way
of doing this.)

I'll make a fresh start with IPC code when I get there.

List the root directory after mounting /.
...
So cool that it works! It's spewing out a bunch of terminal escape sequences
that the OS console obviously doesn't support, but we'll get there too.

Import the "gerbert" kernel I worked on earlier this year.

It's a lot crappier than I remembered it. It's gonna need a lot of work.
