Manual partitioning is broken

[Wuodan]

In the partitioning sub-menu, select the 2nd option "Manually partition ..."
The output of the partitioning tool (cfdisk or cgdisk) ends up in the log file /tmp/pentoo-installer.log

The 'source' of the problem seems to be in sbin/pentoo-installer:

2> /tmp/pentoo-installer.log

if I remove that and remove redirection where cgdisk is called, then cgdisk starts working. But having no log file is no option!

My options:

• replace that 2>log-file with tee
  Some scary process substitution and file redirection and cgdisk shows, but output is slightly borken and keyboard input does not work.

• Find out why vim/nano work in system config ... if they do, cgdisk should too.

• Drop support for manual partitioning.
  Seriously, anyone doing that should be able to do it outside installer. Plus cgdisk/cfdisk are the last tools I would use, only reason I kept them in the installer is cause i thought 'parted' was to complicated. But parted does not work for the same reason.

• Let user edit some json config that I'm preparing to have installer run form config-file ... don't think we want that either.

Without all the:
CONFIG_LIST="$(script)"
that lead to the partition_manual file (2), it works.
But that's the way installer was designed, write CONFIG_LIST to STDOUT, not to a file.
Reason: that list may contain sensitive info to remount partitions.

==> we could move that manual partitioning part to main-menu, then it does not need to return anything.
