My first Linux install was about one year ago. After some missteps, I have used Debian 8 in reasonable satisfaction on the desktop during that year. Now I want to leave 8 in place and do a network install for Debian 9 on the same disk and switch back and forth at boot time. LVM reports as follows:
dan@debian:/$ sudo vgdisplay -C VG #PV #LV #SN Attr VSize VFree debian-vg 1 5 0 wz--n- 976.56g 938.20g Currently, Debian 8 needs less than 40g for me as you can see: dan@debian:/$ sudo lvdisplay -C LV VG Attr LSize ... home debian-vg -wi-ao---- 10.00g root debian-vg -wi-ao---- 8.38g swap_1 debian-vg -wi-ao---- 7.81g tmp debian-vg -wi-ao---- 380.00m var debian-vg -wi-ao---- 11.79gSo there is plenty of disk space for the two Debians and more besides. The question is how to prepare to install 9? My guess is to define another volume group called debian9-vg perhaps but how will this be recognized during network install? I've clobbered stuff before during installs and I'm gun shy. Maybe there is a better way. Any thoughts on this will be appreciated.
