I have a system on which I have installed multiple distros on LVM2 system. It has one PV, one VG and couple of LVs.



Each distro is installed on same PV, VG but has different LVs for their root and home partitions.
Typically for each distro, I have one LV for /root and other for /home partitions on btrfs.



The problem that I am facing is one ubuntu flavour(ubuntu) is not recognizing another flavour(ubuntu-mate, Lubuntu, Xubuntu, etc) but it's very well detecting other linux flavour (say fedora, arch).



In grub2 menu, I always see only one entry for any ubuntu flavour that is installed at last or grub-update is performed on it.



Can any one help me around this?



Regards
Deep
