```
13:16:50 [2]: WARNING: this system does not seem to have LVM2 tools.
```
I have now added `lvm2` to the package lists, so that the logical volume management support is
enabled.

Hamara-Sugam lacks the feature of adding Users and Groups via GUI.
gnome-system-tools is the package required for managing Users and
groups, Date and time, Network options, Services and Shares.
Hamara-Sugam's missing feature was a result of nihility of this package.
Add the package to the tools list to be installed in chroot stage to fix
this issue.
