Combining Mix Use (MU) and Read Intensive (RI) SSD in same Raid array
cn flag

I know you cannot combine mixed drive types in an array eg. SAS/SATA or SSD/HDD. What about identically sized SATA SSD in the MU and RI options?

4x P18434-B21 - HPE 960GB SATA MU SFF SC MV SSD - Mix Use, currently installed
4x P18424-B21 - HPE 960GB SATA RI SFF SC MV SSD - Read Intensive, want to expand with these.

The only difference in spec I can find is the write cycles each one can handle, ...

I am planning on having my application auto-update -- requiring no manual intervention from the sysadmin.

Add some text to curl's user agent string? (i.e. curl with a UA that includes curl's default UA & my text)
bg flag

I am writing a shell script which uses curl(1) to download files. By default curl will set a HTTP User-Agent (UA) to something like curl/7.74.0. I want to be a good internet citizen and set the UA to say what my script is. Since the software that is making HTTP requests is still curl, I would like this user agent to also include the default curl UA.

I can replace User-Agent with -A, but is it possible ...

IPv6 connectivity suddenly lost, IPv6 neighbour router status becomes STALE at the same time. How can I avoid it?
de flag

I have a VM on a host with bridged networking (hence, with its own MAC address). Both host and VM run CentOS. Their network is managed by simple /etc/sysconfig/network-scripts/ifcfg-enpXsY files which contains the static IP addresses. IPv4 works just fine.

I have assigned an IPv6 address to the VM (the host also has one) which is routed correctly in the data centre. Most connections use IPv4, however ...

Why not shorten a single :0000: field in IPv6
jp flag

rfc5952, section 4.2.2 "Handling One 16-Bit 0 Field" goes:

The symbol "::" must not be used to shorten just one 16-bit 0 field. For example, the representation
2001:db8:0:1:1:1:1:1 is correct, but
2001:db8::1:1:1:1:1 is not correct.

The kawamura-03 draft has a hint as to why:

"::" should not be used to shorten just one 16 bit 0 field for it would tend to mislead that there ...
