>Description:
Trying yesterday's trunk (15-Dec-2025) and it seems that post the GCC 14.0 bump the sgimips kernel+ramdisk installer image isn't fitting:

===
#    create  instkernel/diskimage
Calculated size of `diskimage.tmp': 4812800 bytes, 3 inodes
Extent size set to 4096
diskimage.tmp: 4.6MB (9400 sectors) block size 4096, fragment size 512
        using 1 cylinder groups of 4.59MB, 1175 blks, 32 inodes.
super-block backups (for fsck -b #) at:
 32,nbmakefs: Writing inode 3 (work/./netbsd), bytes 4763648 + 1094: No space left on device

Populating `diskimage.tmp'

*** Failed target: diskimage
===


>How-To-Repeat:

My build script:

===
#!/bin/sh

OBJDIR=/data/1/adrian/netbsd/netbsd-obj-sgimips
DESTDIR=/data/1/adrian/netbsd/netbsd-root-sgimips
X_FLAGS="-u -U -j 8"

# build an installer image, hopefully will boot!
./build.sh -O ${OBJDIR} -D ${DESTDIR} ${X_FLAGS} -m sgimips build release iso-image
