Hello all,

I try to set the number of inodes  to create in the filesystem during the installalation with the pressed file.
The same way that mkfs: mkfs -t ext4 -N iNumberOfINodes /dev/XdY ?

Community (debian-user) indicates me this information:

From there I found this file for bullseye:
  https://preseed.debian.net/debian-preseed/bullseye/amd64-main-full.txt >>which contains this stanza which appears to match your description:

### Description: Typical usage of this partition:
#  Please specify how the file system is going to be used, so that
#  optimal file system parameters can be chosen for that use.
#  .
#  standard = standard parameters,
#  news = one inode per 4KB block,
#  largefile = one inode per megabyte,
#  largefile4 = one inode per 4 megabytes.
# d-i partman-basicfilesystems/specify_usage select <choice>
# Possible choices: ${CHOICES}

Which is not what the OP requested, but maybe it helps.  It is the only >>occurrence of "inode" in that file.  I did not check the other two files >>that contain the "contrib" and "non-free" data.

I tryed to adapt like this with this option: **specify_usage{  }** --------------------------------------------------------------------------------------------------------------

But this change nothing after verfication the bytes per inode is 16k in all case. (<bytes-per-inode> = <block count> x <block size> / <inode count>)

Tryed also with -----------------------------------------------------------------------------------------------------------
d-i partman-basicfilesystems/specify_usage select news ----------------------------------------------------------------------------------------------------------

And ugly workaround will be to update inode_ration into  /etc/mke2fs.conf with sed  via

-------------------------------------------------------------------------------------------------------------------------

d-i partman/early_command string \    sed -i 's/inode_ratio = 16384/inode_ratio = 4096/g' /etc/mke2fs.conf
------------------------------------------------------------------------------------------------------------------------

but it apply to all FS.

/etc/mke2fs.con also indicates the values:
--------------------
....
    news = {
        inode_ratio = 4096
    }
    largefile = {
        inode_ratio = 1048576
        blocksize = -1

    }
    largefile4 = {

        inode_ratio = 4194304
        blocksize = -1
    }
.....

Do you know how to use the option *specify_usage* to select the options news for a file system?

Thierry
