Re: FreeBSD 15.0-ALPHA4 Now Available

Hi,

some additional info.

After bsdinstall(8) fails - and asks for new 'try' to is not able to do anything with that error:

+-------------|Error|-------------+
| No disk(s) present to configure |
+---------------------------------+
|            [  OK  ]             |
+---------------------------------+

The disk - needs to be cleaned after fail operation - for example like that:
- https://github.com/vermaden/scripts/blob/master/storage-wipe-clean.sh

Also - I made another test installation and I am able to install FreeBSD on ZFS with only 300 MB of RAM.

Boot: continue with 'vt100' default.

Select 'Live System' option.

Execute these:

root@:~ # kldload zfs
ZFS filesystem version: 5
ZFS storage pool version: features support (5000)

root@:~ # sysctl vfs.zfs.arc.min=33554432
vfs.zfs.arc.min: 0 -> 33554432

root@:~ # sysctl vfs.zfs.arc.max=67108864
vfs.zfs.arc.max: 0 -> 67108864

root@:~ # sysctl vm.pageout_oom_seq=1200
vm.pageout_oom_seq: 12 -> 1200

root@:~ # bsdinstall

I selected PKGBASE and Offline installation.

Then I switched from (BIOS) to (BIOS+UEFI) and installed these System Components:
  [X] base  The complete base system (includes devel)

Stats after install (before reboot):

root@:/ # dmesg | grep -i memory
real memory  = 314572800 (300 MB)
avail memory = 263303168 (251 MB)

root@:/ # top -b -o res
last pid:  2544;  load averages:    1.31,    0.80,    0.34  up 0+00:02:20    18:02:03
10 processes:  1 running, 9 sleeping
CPU:  7.8% user,  0.0% nice, 16.7% system, 12.1% interrupt, 63.4% idle
Mem: 3588K Active, 11M Inact, 6376K Laundry, 148M Wired, 5800K Buf, 89M Free

     29M Compressed, 65M Uncompressed, 2.24:1 Ratio

I tried the same with 256MB of RAM - but it fails.


About that '^H' problem - in vt100 mode when I hit [ENTER] key to change ZFS options I do:
- hit [LEFT] arrow as many times to be in that place:

                ><
-o compression=on -o atime=off

Then I hit [BACKSPACE] key two times so its like that:

              ><
-o compression= -o atime=off

Then i type [Z][S][T][D] so it looks like that:

                  ><
-o compression=zstd -o atime=off

... and I hit [ENTER].



Hope that helps.

Regards,
vermaden

- even as I selected 'xterm' at the beginning - it starts with 'vt100' mode
- the 'xterm' (or any other) should be PRESERVED in subsequent
